Hey class, here are some helpful worksheets you all might like to do in order to get practice on certain areas. I have the keys, and as you complete each one you may e-mail them to me or print them off and hand them in in class for some extra credit. I will be accepting one a week for extra credit and if you need to do more of them to help your understanding of the section than feel free to do them and I will grade them. Good luck and happy studying!
